I've been playing a campaign as the empire and have noticed that Antimatter regeneration seems to set very very low. I did a test and upped the game speed and my ships still barely regenerated antimatter.

 

I'm not sure if this is a bug or if it's just something that I'm missing on how to address this issue.

 

Regardless, Love the mod and all the other you've done. Keep up the great work!

They are deliberately slowed, so you have to go back to certain buildings in order for them to regenerate at a higher rate. I think there are reports that some of the buildings are working as intended yet
